How to freeze potatoes, and other things, I suppose

Maybe I suck at parboiling, but I have never successfully frozen potatoes. They wind up watery and mealy and sometimes black. I've read instructions on prepping, parboiling, and freezing, but it's never worked out for me. What secrets do Ore-Ida have that allow them to freeze potatoes in various forms and have them come out edible?? Anyone had any success freezing potatoes?

you want to get them to freeze as quickly as possible afaik about freezing things. the quicker it freezes the less integrity of the product will be compromised/lost. i still don't know if you can do this successfully in a home kitchen with potatoes. but after you parboil, cool them down on as quickly as possible (if you cool in the fridge preferably on a metal cookie sheet they'll take less time to freeze). then i'd put the sheet pan they're cooling on in the freezer and get them well frozen before putting into a storage container.
seems like a huge hassle. why do you want to do this?

Since they're not a "more expensive out of season" item, it never occurred to me to try. I think frozen french fries are par-fried, not parboiled. xp

I've only successfully frozen (partially and fully) cooked potatoes. Ore-ida cooks and coats with oil before freezing so all you're doing is reheating/crisping.

what happens when you freeze a raw potato?

it goes gross and sweet iirc
